Confidence interval precision: We know that narrower confidence intervals give us a more precise estimate of the true population proportion. Which of the following could we do to produce higher precision in our estimates of the population proportion? 1. We can select a higher confidence level and increase the sample size. 2. We can select a higher confidence level and decrease the sample size. 3. We can select a lower confidence level and increase the sample size. 4. We can select a lower confidence level and decrease the sample size.
